The high incidence of hearing impairment in the Arabic-speaking population
in Israel, as well as the use of advanced aural rehabilitation devices, mot
ivated the development of Arabic speech assessment tests for this populatio
n. The purpose of this paper is twofold. The first goal is to describe feat
ures that are unique to the Arabic language and that need to be considered
when developing such speech tests. These include Arabic diglossia (i.e., th
e sharp dichotomy between Literary and Colloquial Arabic), emphatization, a
nd a simple vowel system. The second goal is to describe a new analytic spe
ech test that assesses the perception of significant phonological contrasts
in the Colloquial Arabic variety used in Israel. The perception of voicing
, place, and manner of articulation, in both initial and final word positio
ns, was tested at four sensation levels in 10 normally-hearing subjects usi
ng a binary forced-choice paradigm. Results show a relationship between per
cent correct and presentation level that is in keeping with articulation cu
rves obtained with Saudi Arabic and English monosyllabic words. Furthermore
, different contrasts yielded different articulation curves: emphatization
was the easiest to perceive whereas place of articulation was the most diff
icult. The results can be explained by the specific acoustical features of
Arabic.
